Use synonyms for your concepts
**including both more specific and/or more general terminology can be useful
so, not just "air pollution", but also: emissions, particulates
**in chemistry-related searches, it's often good to include the chemical symbol:
**are there useful abbreviations?
in searching chlorofluorocarbons (another pollutant example) , you would also want to use CFC (s)
Use the wildcard symbol (often the asterisk (*)) when available
**pollut* >> retrieves pollution, pollutant, pollutants
Use quotation marks to search for an exact phrase
For example: "mercury emissions"
Use Boolean operators when allowed
AND – use to combine concepts (when both must be present)
OR – use for synonyms (when either term could be present)
Use parentheses to group terms
Put it all together:
(global warming or climate change) AND (chlorofluorocarbon* or CFC* or freon*)
Keep your eyes open for these several journals that cover a broad array of science topics and that often offer less-technical content. You can browse these, or search for specific topics using the databases listed below.
Look for "review
articles" when you're starting to learn about a new topic. In addition to summaries, they also provide lists of
key references. Besides the Annual Reviews database linked below, find them by searching most
databases (often there is a "review" limiter), or look for the word,
"review" in the title of the article.
